Overview of this book

The history of graphical application development is long and complicated, with various development challenges that persist to this day. The mix of technologies involved and the need to use different programming languages led to a very steep learning curve for developers looking to build applications across multiple platforms. In Building Cross-Platform GUI Applications with Fyne, you'll understand how the Go language, when paired with a modern graphical toolkit such as Fyne, can overcome these issues and make application development much easier. To provide an easy-to-use framework for cross-platform app development, the Fyne project offers many graphical concepts and design principles that are outlined throughout this book. By working through five example projects, you'll learn how to build apps effectively, focusing on each of the main areas, including the canvas, layouts, file handling, widgets, data binding, and themes. The book will also show you how the completed applications can then be run on your desktop computer, laptop, and smartphone. After completing these projects, you will discover how to prepare applications for release and distribute them to platform marketplaces and app stores. By the end of this book, you'll be able to create cross-platform graphical applications with visually appealing user interfaces and concise code.

Summary

This chapter stepped through the details of how layouts work, the details of all the built-in layouts in the toolkit, and when to use them. We also saw how simple it is to combine multiple layouts and created our own custom layout to add a bit of flair to our image browsing application.

We also explored how to adapt file handling code to work across all platforms using the URI and ListableURI types. Using this knowledge, our image browsing application is now compatible with all desktop and mobile platforms. With this knowledge of how to lay out applications and avoid assumptions about a traditional filesystem, you can now ensure that your apps will function correctly on any supported platforms, mobile, desktop, and beyond.

While we have created a complete application using just canvas primitives and layouts, it is possible to build much more complex applications using the widget package, which we will look at in the next chapter.
